Product Introduction 1

Home epidemic prevention Pay attention to indoor air quality

In this special period, we should not only pay attention to

personal hand hygiene, wash hands frequently, cover our

mouth and nose with tissue paper when sneezing or

coughing, keep the room clean, but also maintain indoor air

circulation.

In addition to opening windows for air ventilation, are there

any other ways?

Academician Zhong Nanshan suggested: Air purifiers

can be considered to use if conditions permit!

Right home air quality optimization program

Open window for air ventilation + professional air purifier

Open window for air ventilation: It can allow the

indoor environment to form convection to ensure indoor

air circulation and ventilation, but it cannot kill viruses

and other harmful substances in the air;

Gree air purifier: It can eliminate and purify viruses,

bacteria and other harmful substances in the air in the

house .

Indoor air sterilization

Why do we need an air purifier after opening the window for

ventilation?

➢ Whether it is indoor or outdoor, the air contains a lot of harmful

substances. Opening the window is mainly to ensure indoor air

ventilation. If you want to create a better healthy indoor

environment, except air ventilation, you also need to eliminate

the virus and filter harmful substances in the air;

➢ As for the places with severe haze or poor air quality, indoor

PM2.5 may increase when outdoor air comes into the room;

➢ In spring, there may be allergens (such as pollen) in the outdoor

air, and susceptible people will be allergic;

Indoor air sterilization

Academician Li Lanjuan stated that the novel coronavirus is afraid of alcohol and high

temperature:

1. Coronavirus will die at 56 ° C for 30 minutes;

2. Ether,75% ethanol, and chlorine-containing disinfectants can effectively inactivate the virus;

Indoor air sterilization

Prohibit spraying much 75% alcohol in the house for air sterilization

Li Lanjuan, an academician of the Chinese Academy of Engineering, recently announced that 75% alcohol can eliminate

the novel coronavirus. Since then, many people began spraying with a lot of alcohol in the house, which is the wrong

disinfection method. Yue Guojun, an academician of the Chinese Academy of Engineering, stated in an interview that

spraying much 75% alcohol in the house for air sterilization is prohibited. If the alcohol in the air exceeds 3%, it may

cause fire or explosion. Therefore, the alcohol in the air must be less than 3%.

Use alcohol for air sterilization?

Product Effect2

Product Effect

1.Novel coronavirus test in Wuhan

The elimination of "novel coronavirus" was verified

in the CT Examination Room of Wuhan Jinyintan

Hospital:

After 1 hour of work, the nucleic acid content of novel

coronavirus (CT value 39) was significantly lower than

that before purification (CT36.4), that is, the elimination

rate of virus in the air was more than 99%; so the virus

content in the air decreased by at least 10 times,which

indicates that the air purifier had a significant elimination

effect on novel coronavirus in the air.

2. Test results of Guangzhou Institute of Respiratory Diseases

Guangzhou Institute of Respiratory Diseases verifies the elimination effect for "coronavirus" :

By comparison, no coronavirus is detected in the experimental sample . The virus-elimination rate

for coronavirus is 99.99%.

Product Effect

3.Test result of Chinese Academy of Sciences

Verify the removal effect for "all kinds of particulate matters" (including fine particles)

The total number concentration of particles with aerodynamic diameter of 20~700nm in a confined space of 60.6m3 is

decreased from 2,828.3 particles/cm3 to 84.5 particles/cm3 within 55min. 50 particles/cm3 aerosol particles are removed

per minute on average.

4.Test result of Beijing Dingblue Technology company

Verify the removal effect of "bioaerosol"

The concentration of biological particles (> 1 micron) in a confined space of 35m3 was decreased from 1.5x 100,000 /L to

zero within 4.4min. 100 million biological particles are removed per minute on average.

Technical Principle3

Novel coronavirus structure:

Protein + genetic material

The researchers found that the S protein on the

envelope of the coronavirus plays a key role in

virus recognition and invasion.

Eliminate the virus by high

temperature of 56℃continuously and completely

block and reduced the novel

coronavirus in the air

Technical requirements for eliminating novel coronavirus

The technology uses corona discharge to

produce plasma, which destroys bacteria and

viruses and inactivates them. The inactive

bacteria and viral debris are collected together

The First Safeguard: CEP Plasma Constant Efficiency Purification Technology

Initial filterFiltrate hair, scurf of human and animal, coarse particles, etc.

Generation polePlasma is formed and ion wind is generated kill or decompose harmful substances, e.g. bacteria; charge the particles to collect and absorb them

Collection poleCollect harmful substance, e.g. dust, dead bacteria.

Ozone revivification

screenRevivify the residual

ozne into fresh air.

Frech air

The second safeguard：HEPA13 filter, with high-efficiency filtration

HEPA13 filter:

Filtration efficiency of HEPA13 filter ≥99.95%

KXJFA300-B01 adopts H13 filter

The third safeguard: high temperature inactivation by smart precise temperature control system

Gree's self-developed smart temperature control

system can accurately control the temperature,

keeping the surface of the filter at a high temperature

of above 56 ° C, and eliminated the novel

coronavirus .

56℃

The intelligent temperature control system independently developed by Gree can accurately and precisely

control the temperature, so that the surface of the filter can maintain the temperature above 56 ℃, which can

eliminate the novel coronavirus and prevent the secondary pollution.
